When you think of diseases endangering women today, you may not initially think of coronary artery disease (CAD), but you should. CAD — a leading cause of heart attacks, heart failure, arrhythmia (abnormal heart rhythm), or even death — is not just a man's disease. CAD is just as likely to occur in women, and the risk of a blockage in your heart arteries increases significantly as women age. CAD is a serious condition that can be less obvious in women, which is why you need to listen to your body and be an advocate for your own heart health.
